For example:
Host bernadette
HostName my.ip.add.ress
Port 10022
HostKeyAlias bernadette
CheckHostIP no
Host raymonde
HostName my.ip.add.ress
Port 10023
HostKeyAlias raymonde
CheckHostIP no
Now you should be able to do "ssh bernadette" and "ssh raymonde".
Personnally, I use something like dnsalias.org to register my hostname
so if the IP address changes I don't need to change config files
(set HostName foobar.dnsalias.org - where foobar is the name you registered)
